[Dovecot] help with authentication - cpanel
by allan hardy 22 Jul '06

22 Jul '06

I am trying to install dovecot as a second pop3 service in my RH9 system. It is a Cpanel based system using Courier for primary IP By primary I mean all the other domains use courier on xxx.xxx.xxx.21 port 110 I have a domain with special pop3 needs that is dedicated to xxx.xxx.xxx.22 port 110 The two mail systems are installed, I can tell via telenet that dovecot is listening and responding on the desired IP and port Cpanel is the tool being used by all domains to create mail accounts and hence setting the 'policy' for the mailboxes, userdb and passdb information. I am trying to make dovecot use those files and can't get past authentication. What I guess I don't know is the encryption type being used by Cpanel Any help appreciated.!!!! What Cpanel appears to do for authentication is use a passwd and shadow file for each domain, placed as follows: /home/accountname/etc/domainname/passwd holds the list of mail accounts names /home/accountname/etc/domain/shadow holds the passwords This is the message log from a telnet session on local machine: dovecot: Jul 22 13:45:27 Info: auth(default): client in: AUTH 1 PLAIN service=POP3 secured lip=xxx.xxx.179.22 rip=xxx.xxx.179.22 resp=AGFsbGFuAHRlc3Q= dovecot: Jul 22 13:45:27 Info: auth(default): shadow(allan,xxx.xxx.179.22): password mismatch dovecot: Jul 22 13:45:29 Info: auth(default): client out: FAIL 1 user=allan dovecot: Jul 22 13:45:36 Info: pop3-login: Aborted login: user=<allan>, method=PLAIN, rip=xxx.xxx.179.22, lip=xxx.xxx.179.22, secured ~ This was in the shadow file: ---Shadow file entry allan:$1$V0lG6T6P$eNQoX3J3N5RJNxT5yH8gz1::::::: These are my relevant (At least I think they are relevant) dovecot.conf settings: disable_plaintext_auth = no ssl_disable = yes auth default { mechanisms = plain login anonymous passdb shadow { /home/xxxxxx/etc/xxxxx.com/shadow } userdb passwd-file { # Path for passwd-file args = /home/xxxxxxx/etc/xxxxx.com/passwd } --PAM is commented out As a side note, I tried to see if I could tell from the courier setup how it was authenticating. The courier/etc/pop3d file was set POP3AUTH="" And there was a note "To advertise the SASL capability, per RFC 2449, uncomment the POP3AUTH variable" So it this may indicate sasl is being used, what ever that means

[Dovecot] Dovecot and quotas
by mikael 22 Jul '06

22 Jul '06

Hello, I have succesfully installed dovecot version 1.0.rc2 on my Debian Sarge. I have configured quotas (just for tests) like this : == dovecot.conf == ... auth default { mechanisms = plain passdb pam { } userdb passwd { } } protocol imap { mail_plugins = quota imap_quota } plugin { # quota = 10 Mb quota = dirsize:storage=10240 } ... ================== Quotas works without problem : 10Mb for all users... But i would like quotas per user and kept thi default value of 10Mb... How to override this default value ? How to do peruser-quota with "passwd" userdb (or "passwd-file") ? Really thanks for your help, -- Mikaël,

[Dovecot] cmusieve plugin
by Stuart Sears 21 Jul '06

21 Jul '06

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi guys I have been doing a lot of searching, but maybe I am being dim (not unheard of!). I have dovecot-1.0rc2 built and running on Fedora Core 5. The wiki page (dated yesterday) states that I need the cmusieve plugin to use sieve scripts with the dovecot lda. Is this a new development? They seem to work quite happily on my soon-to-be retired 1.0-beta7 debian box without an extra plugin. secondly, if it is now necessary, where do I get this plugin from? (this may be the dim part) I have a cvs checkout of the dovecot sources, but I see nothing obviously connected to cmusieve anywhere in the source tree If this is in a different module, then can someone let me know the name of it, so that I can check it out of CVS as well?

[Dovecot] Migrating to dovecot
by Johann Spies 21 Jul '06

21 Jul '06

I do not have much experience in setting up imap servers - only that I have tried several and experienced the same problem with all of them. I suppose that is because I do not really know the in's and out's of an imap server. What I want to do is to setup an IMAP server on my PC with full access to all the emails already there in a maildir structure. I have the following setup: fetchmail -> procmail -> maildir exim for outgoing mail. When I install an imap server, I loose access to my present emails in ~/Mail and most imap-servers (dovecot included) seems to create a new structure within ~/Mail. ~/Maildir is a symlink to ~/Mail. Now my questions: 1. How do I set up dovecot to serve the present maildir to the user? 2. Related to 1: How do I migrate my emails to the new imap-maildir structure without losing any? 3. How would my present procmail-setup change? At the moment I have entries like the following: MAILDIR=$HOME/Mail # you'd better make sure it exists DEFAULT=$MAILDIR/Ander/new # completely optional :0: * X-Spam-Flag: YES saspam/new :0: * ^List-Id: <users.spamassassin.apache.org> spamassassin/new ...

[Dovecot] Soft limit quota
by Philipe Gaspar 20 Jul '06

20 Jul '06

I'm using dovecot on our new mail server and it is pretty good. But I have a problem regarding quota limits, I am using quota plugin on imap, pop3 and LDA, the deliver agent blocks new messages for delivery, like hard quota. I'd like to use LDA with quota plugin regarding soft quota. Thanks for any clues, -- Philipe Gaspar Universidade Salvador Fone:+55 (71) 3273-8592

[Dovecot] Patch suggestion
by Renaud Allard 20 Jul '06

20 Jul '06

Hi, Would it be possible to make a change in the configure file to search for gssapi.h in <kerberosV/gssapi.h> if it fails to find it in <gssapi/gssapi.h>? That would allow to compile dovecot with gssapi easily on OpenBSD without patching it.

[Dovecot] making Dovecot match Courier POP3 UID's
by Jeff Tucker 20 Jul '06

20 Jul '06

Hi, guys. I've read the information in the Wiki about making dovecot's UID's match Courier's UID's in the POP3 server, so that a UIDL command on either server will return the same UID's for the same group of messages. However, what I've read doesn't match what I'm seeing in Courier. Courier appears to keep the UID numbers for messages that it uses for the POP3 server separate from the UID numbers for the IMAP server. Courier has a file: courierpop3dsizelist which has a line for every message, like: 1129610881.6075832619.blade4:2,S 2361 1478:1065670602 1129727025.1168007000.blade1:2,S 14718 1479:1065670602 1130005953.3295720403.blade5:2,S 1554 1481:1065670602 1130108068.0849623942.blade5:2,S 8246 1482:1065670602 The first column is the maildir filename, the last column is the UID that the POP3 server uses and the UID validity. Both are used to create the UID number returned by UIDL. The IMAP server uses a completely different UID number that's stored in courierimapuiddb. So, it seems to me that dovecot can't ever match Courier's UID numbers for the POP3 server unless it reads and interprets this courierpop3dsizelist file. My Courier-IMAP installation is Courier-IMAP 4.0.6. Any ideas? This is a real hassle because it means I can't switch the POP3 server from Courier to Dovecot or, if I do, lots of my users will download every message again which is just unacceptable. Thanks Jeff

[Dovecot] proxy performance
by Vincent Fox 19 Jul '06

19 Jul '06

Can anyone speak to experience using Dovecot proxy to frontend for multiple back-end servers in a "large" environment? We have 50,000+ mailboxes spread across 10 POP/IMAP servers. We'd like to be able to put in a front-end setup on our load-balancer of 4 dual-CPU Sun systems. I am a bit concerned about performance issues although from what I have read the proxy can be set not to fork, which improves performance a lot. Still concerned about whether SSL loading will be an issue. We'd like to use LDAP to look up the reference to which mail-store a user is on. I see that the Wiki refers to SQL. The mailing list indicates passwd-file also works. Not clear about LDAP.
